Comparing 2 standards across 7 specifications. 7 key differences identified.
Comparing:
DisplayPort 1.0
DisplayPort 1.2
DisplayPort 1.0, approved by VESA on May 3, 2006, was the original version of the royalty-free digital display standard. Its High Bit Rate (HBR) mode delivered 10.8 Gbps raw bandwidth across 4 lanes, with hot-plug detection and embedded digital audio built in from the start.
DisplayPort 1.2, released January 7, 2010, doubled maximum bandwidth to 21.6 Gbps via a new High Bit Rate 2 (HBR2) mode, enabling 4K at 60Hz for the first time. Its headline feature, Multi-Stream Transport (MST), lets multiple monitors daisy-chain from a single DisplayPort output.
